车用低比例甲醇汽油的使用性能研究

摘要

Combustion performance of the low proportional methanol gasoline used in 4G15S gasoline engine and Hyundai ix35 car was studied .Taking M15 and M25 methanol gasoline as test samples ,burning characterized data about the dynamic performance ,economy ,stability and discharge were tested and compared with 93# gasoline .The results showed that the engine power increased ,the acceleration time and acceleration distance decreased after burning M 15 and M25 methanol gasoline ;both effective fuel consumption rate and average fuel consumption increased ;the stability is as the same as 93# gasoline;and CO and HC emissions of the tail gas decreased obviously .Research conclusions confirmed M 15 and M25 methanol gasoline had good service per-formance ,w hich could provide some reference basis for the practical application of the low pro-portion methanol gasoline .%研究低比例甲醇汽油在4G15S汽油发动机和现代ix35小型客车上的使用性能。以M 15、M 25甲醇汽油作为试验样品，测试燃用时的动力性、经济性、平稳性和排放性等特征数据，并与燃用93＃汽油进行对比分析。结果表明，燃用M 15、M 25甲醇汽油后，发动机功率增大，加速时间和加速距离减小；有效燃料消耗率和平均燃料消耗量均增加；平稳性与燃用93＃汽油时相同；尾气中CO和HC排放量明显下降。研究结论证实，M15、M25甲醇汽油使用性能良好，为低比例甲醇汽油的实际应用提供了一定的参考依据。
